efaq: Meta key does not work in xterm

 
 9.13 Why doesn’t my <Meta> key work in an ‘xterm’ window?
 =========================================================
 
 Single-Byte Character Set Support (emacs)Unibyte Mode.
 
    If the advice in the Emacs manual fails, try all of these methods
 before asking for further help:
 
    • You may have big problems using ‘mwm’ as your window manager.
      (Does anyone know a good generic solution to allow the use of the
      <Meta> key in Emacs with ‘mwm’?)
 
    • For X11: Make sure it really is a <Meta> key.  Use ‘xev’ to find
      out what keysym your <Meta> key generates.  It should be either
      ‘Meta_L’ or ‘Meta_R’.  If it isn’t, use ‘xmodmap’ to fix the
      situation.  If <Meta> does generate ‘Meta_L’ or ‘Meta_R’, but ‘M-x’
      produces a non-ASCII character, put this in your ‘~/.Xdefaults’
      file:
 
            XTerm*eightBitInput:   false
            XTerm*eightBitOutput:  true
 
    • Make sure the ‘pty’ the ‘xterm’ is using is passing 8 bit
      characters.  ‘stty -a’ (or ‘stty everything’) should show ‘cs8’
      somewhere.  If it shows ‘cs7’ instead, use ‘stty cs8 -istrip’ (or
      ‘stty pass8’) to fix it.
 
    • If there is an ‘rlogin’ connection between ‘xterm’ and Emacs, the
      ‘-8’ argument may need to be given to rlogin to make it pass all 8
      bits of every character.
 
    • If Emacs is running on Ultrix, it is reported that evaluating
      ‘(set-input-mode t nil)’ helps.
 
    • If all else fails, you can make ‘xterm’ generate ‘<ESC> W’ when you
      type ‘M-W’, which is the same conversion Emacs would make if it got
      the ‘M-W’ anyway.  In X11R4, the following resource specification
      will do this:
 
           XTerm.VT100.EightBitInput: false
 
      (This changes the behavior of the ‘insert-eight-bit’ action.)
 
      With older ‘xterm’s, you can specify this behavior with a
      translation:
 
           XTerm.VT100.Translations: #override \
             Meta<KeyPress>: string(0x1b) insert()
 
      You might have to replace ‘Meta’ with ‘Alt’.
